Application filed Gotoher 1.9, 1812.

T aZZ whom it may concern I Be it known that I, FREDERICK BISHQPRIG, a subject of the King of Great Britain, residing at lliil liiclueod street, in the city of Ottawa, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Machines for lldanutacturing Outer Covering Material for Packages, of which the following is a specification.

My invention relates to improvements in machines for manufacturing outer covering material for packages, and the object of the invention is to devise a machine which will coat paper on one side with asphaltum or some similar substance and at the same time embed laths therein; a further object is to construct a machine which will manufacture a covering material for packages which will he impervious to water and air, and yet cheap in construction and durable.

The invention consists it a ma chine havingmeans for feecli the paper therethrough, a steam jacketed kettle containing asphaltum .ll' other similar substance, asteam heated teed roller adapted to bear against one surface ot the paper. av guiding roller around which the paper extends, a second steam heated roller adapted to bear against the underneath side of the paper when same is passing around the guiding roller, said second steam heated roller rolling oil the superfluous asphaltum, means for varying the thickness of the coating" material on the paper, means for feeding the lathe down on the coated surface of the paper partially embedding same into such coating, and means for trimming the edges of the material after the laths have been attached thereto, all as hereinafter more particularly described and illustrated in the drawings in which Figure i represents a side ot the machine. Fig. *2. is an end vie the end from whi h the tin passes out. Fig. is a side the ineans't'or the laths down the coated surface of the paper, and Fl is a side view of a modified lfeedind Specification of Eetters Eetent.

mechanisn. Fig. 5 is detail of the rod 11 and its connections. Fig. 6 is a detail showmg the relative widths of the roller and the paper.

Like characters of reference represent corresponding parts in the diiferent views.

1 is the roll of paper mounted on a spindle 2.

3 is the which the cured.

is the kettle or trough containing asplialtum or other similar material.

5 and 6 are guiding rollers for the paper 1 under the kettle T is a guiding roller for the paper on top of the frame.

8 is the steam-heated roller designed to dip into the asphaltum.

9 is a guiding roller journaled in supports 10 which are pivotally connected to the main frame 3.

Z is a second steam heated roller bearing against the paper.

11 is a rod having a hooked shaped lower end 11, and 12 is an operating lever pivotallv connected to the frame and having a depending crank 13 "formed thereon. The rod 11 is pivoted at its lower 11 to the crank 13, and the upper end extends through a lug" 141 on the supports 1O.

15 is a ring on the upper end of the rod adapted to near against. the lugs 14 on the supports l0.

16 is a frame for supporting the lath feeding mechanism.

17 and 18 are superposed rollers, the upper having a plurality of toothed portions 19 between the teeth of which the laths rest.

main frame or" the machine to roll of paper 13 detachably se- 20 is the shaft of the roller 17, said shaft shaft '14 meshing with a pinion 9 6 on a shaft 2.7 to which the driving pulley 28 is conne ted. I

is a table abo e the flooring 30 over which the laths 31 are fed down a chute 32. The chute 32 supported on brackets 33 mounted on the roller shaft 20. In the present instance, the roller 17 revolves in a contra-clockwise direction.

34 is a roller revolving in a clockwise direction, said roller being situated at the bottom of the chute 32. v

are suitablycurved horns extending around part of the roller 17 and 36 is a link pivotally conr. acted to the horns and brackets 33.

37 is a 'gea 1" connected to the roller 34 and designed to be suitably driven.

38 and 39 are two rollers similar to the rollers 17 and 18 and mounted on a suitable frame 40, said upper roller 38 being mounted in bearings 41 inthe top of the frame 40 which permit the roller 21 certain amount of vertical movement. 38 is, howeven smooth instead of toothed.

42 are brackets secured to the frame 40 and cari ying' a. cross shaft having the trim-- ming saws 43 mounted thereon.

45 is a curved plate down which the finished material is discharged from the machine.

In the modified form of 'lath feeding meehanismshown' in Fig.4, 46 are bands of flexible material connected at the bottom to a suitable pivoted hook 47 thetop of the flexible material extending around pulleys 48 and -19; and 50 is a suitable weight at tached to the ends of the flexible material.

The operation of the machine is as follows: The paper 1 from the roll runs around the rollers 5. 6 and-7 and is coated with the coating substance by the steam heated roller 3. It then passes betw en the rollers 9 and Z and around over the fo mer. The roller Z takes oil the superfluous coating substance. -Thc thi :kness of the coating can be varied by varying the position of the roller 9 relatively to the roller Z. This can be done by operating the lever 12. The paper then runs between the rollers 17 and 18 and the laths 31 are carried down the chute 32 dropping in between the teeth 19 on the roller 17. The roller 34 assists this O ]')@I'.'ltl()ll. insuring the laths dropping in the correct position. Theroller 17 revolving carries the laths around the same to the bottomwhere they are embedded in the coated surface of the paper 1.. The laths are prevented fron'i falling 011' the roller 17 by the horns 35 or the band 46. The distance between the horns or bands and the roller 17 is variable by the connections of thelower ends of the horns to the brackets 33. or the. flexible bands 46 The roller in order that should a thick lath be fed onto the roller 17 it will not be caught between the horn and the roller as would otherwise occur. The roller 17 and the lath feeding mechanism attached thereto, float on the tached to the frame 40 as is also the plate 45.

Thesaivs trim the margin off the paper, it being understood that the coating rollers do not extend the full width of the paper but leave a small margin on each side in order I that the coating material will .not spread and foul the roller 18. What I claim as my inventitn is:

1. In a machine for manufacturing outer covering material for packages, compr s ng 7 a chute .for laths, a plurality of superp ised rollers below the chute, se$ of teeth extend ing around the periphery of theupper roller, and a roller rotating in the oppositedirection to the direction of rotation of the up-' per roller and cotiperating therewith to} feed the laths. said roller being situated adjacent to the bottom of the lath chute as and for .the purpose specified.

2. In a machine for manufacturing outer covering material for packages. comprising a chute tor laths. a plurality of superposed ollers helou the chute, sets of teeth extending around the pCIl}')llCl' V of the upper roller a roller rotating in the opposite direction to the direction of rotation of the upper roller and cooperating thereivith to feed the laths, said rollers being situated adiacent to the bottom of the lath chute, suitably curved horns for preventing the laths falling off the upper roller upon rotation of thesame.

and hraelH-ts securing the chute to the shaft of the upper roller, adjustable means for se-. .rurmg the upper ends of said horns to said paper, superimposed rollers between which the paper is adapted to pass, the upper roller floating and having a plurality of toothed portipns, a chute for feeding the laths onto the upper floating roller, said chutebeing carried with the floating roller and floating itself therewith, and a second pair of superimposed rollers adanted to force the laths my hand in the presence of two witnesses.
